'''NOTE:''' For the procedures below, most will require '''root''' user privileges.
In order to speed up the entire process, you should backup the following files somewhere safe:
/etc/greyhole.conf
This will allow you to rebuild your [[Greyhole]] Storage Pool much faster without needing to rebuild all links in your share before they can be used.
* Before re-installing Fedora/Ubuntu, please disconnect all data drives. This will prevent you from potentially destroying any data during the re-installation process.* Install Then, install Fedora/Ubuntu and Amahi using our installation guide. * Connect [http://docs.amahi.org/ubuntu-12.html Ubuntu]* [http://docs.amahi.org/fedora-19.html Fedora] Next, connect your data drives back to your server.* Use , then use the contents of your previous ''/etc/fstab '' to mount your data drives in their old paths(hint: copy and paste the lines that have mount points in '''/var/hda/files/drives/'''). When you're finished, verify the mount points exist: ll /var/hda/files/drives If they do not, you will need to create them (replace ''drive1'' with what was reflected in ''/etc/fstab''): mkdir -p /var/hda/files/drives/drive1 Now you are ready to mount the drives with: mount -a If there any errors, <u>'''DO NOT'''</u> continue until they are resolved. :'''NOTE:''' This would allow you to remount the drives on the previous paths in your previous installation. For example, if you have one 2TB and one 3TB harddrive, and they were mounted as /var/hda/files/drives/drive1 and /var/hda/files/drives/drive2 repectively, it would be more efficient to remount your data drives on your new Amahi installation in the same locations. However, if you didn't backup your fstab, simply remount the drives like you were installing them for the first time using [[Adding_a_second_hard_drive_to_your_HDA#Mount_Hard_Drive|hda-diskmount]].
Note<blockquote>{{Warning|Warning: This would allow Before you to remount continue, you should check the drives on ownership of the previous paths in your previous installation.

This can be done by copying and pasting all of the mounts for your Greyhole Storage Pool into the /etc/fstab of your new Amahi installation. 1stadminuser:users

Also select the correct number of extra copies desired (without the app, you will have to add them manually in ''/etc/greyhole.conf''). '''NOTE:''' If you don't remember all of your original shares, you can check your old /etc/greyhole.conf file (which includes the extra number of copies) or within run the "following: ls -1 /var/hda/files/drives/*/gh" folder found at the root of your data drives./ | grep -v : | sort -u * Run Greyhole's fsck command to rebuild your shares: greyhole --fsck Until this completes, some of your files will be missing from your shares.
